The delivery capability of power amplifier depends on how instantaneous the current supply is. That’s why the power supply for the MA-9S2 was completely revamped to give it a truly instantaneous current supply capability that has been increased three times as much compared to any Marantz product designed before. ENGLISH MAIN FEATURE OF PRODUCT 7 Fully balanced monaural power amp To minimize the influence of strong “kick back current” occurring from the loudspeaker system, the circuit for the power amp consists of two amplifiers giving a voltage gain amp of 23dB, in a push-pull balanced construction, for the final buffer amp of 6dB. 7 HDAM SA The feedback impedance of the Current Feedback circuit was reduced to its minimum to make it faster. We developed a new Hyper Dynamic Amplifier Modules (HDAM), a separated module operating as a buffer for the amplifier. 7 Choke input system The power supply of the voltage gain amplifier’s adopted choke input system has few ripples and is durable with load changes. This can prevent noise from the amplifier as well as reduce noise from the primary winding, resulting in a clean power supply. 7 Ultra low impedance amplifier The buffer amplifier’s power supply block, which supports the high current delivery capability, uses a capacitance input system to realize very low impedance. The new developed toroidal power transformer, the low impedance electrolytic capacitors, the very large gauge internal wiring, and the thick pattern PWB all contribute in supplying the required power. 3 MA-9S2 UN DFU 01 Eng 1/3 Page 3 06.8.9, 1:34 PM Adobe PageMaker 6.5J/PPC ENGLISH CONNECTIONS Connection 1 Stereo Bi-wiring Connection :Audio signal ID NO. 1 2 3 Set to "1". 4 5 PUSH 6 SC-7S2 PUSH MODE or STEREO BI-AMP Set to "STEREO". or ATTENUATOR (-dB) -3 ATTENUATOR (-dB) 0 -3 Set to "0". -6 0 Set to "0". -6 -9 -9 -12 -12 MA-9S2 -∞ MA-9S2 -∞ for Lch PUSH Remove the short bar. for Rch PUSH MF / HF MF / HF LF LF Speaker Remove the short bar.

Is the control (pre) amplifier or input source wrongly set? 6. Are you using the player in the wrong way? 7. The protective circuit of this unit may have worked. Shut power OFF, wait 1 minute or more, then reactivate the power. ABOUT THE PROTECTIVE CIRCUIT This unit incorporates a protective circuit that protects the amplifier circuit and speaker system against damage. If the protective circuit works, the power indicator in the meter flashes, and sound is muted (no sound). This protective circuit works in the following cases. 7 If the amplifier overheats In the following cases, the amplifier will overheat and the protective circuit will work . • If the unit is used with the ventilation blocked or obstructed • If speakers of less than 4 Ω impedance are used • If the unit is used for an extended period of time under excessive signal input. MAINTENANCE The section describes the care and maintenance tasks that must be performed to optimize the operation of your Marantz equipment. 7 Cleaning of equipment external surfaces The exterior finish of your unit will last indefinitely with proper care and cleaning, Never use scouring pads, steel wool, scouring powders or harsh chemical agents (e.g., lye solution), alcohol, thinner, benzine, insecticide or other volatile substances as these will mar the finish of the equipment. Likewise, never use cloths containing chemical substances. If the equipment get dirty, wipe the external surfaces with a soft, lint-free cloth. If the equipment becomes heavily soiled: • dilute some washing up liquid in water, in a ratio of one part detergent to six parts water. • dip a soft, lint free in the solution and wring the it is damp. • wipe the equipment with the damp cloth. 7 At power ON It takes approximately 8 seconds for the amplifier circuit to stabilize after the power is turned on, during which time the protective circuit works and sound is muted (no sound). Also during this time, the power indicator in the meter flashes. Once the amplifier circuit has stabilized, the protective circuit is released, and sound can be heard. 7 If overcurrent flows to the amplifier circuit (Overcurrent protection) If overcurrent flows to the amplifier circuit because of excessive signal input or if the unit is used with speakers of less than 4 Ω impedance connected to it, overcurrent is detected and the protective circuit engage. The protective circuit also works if the speaker cables are accidentally shorted. The power indicator in the meter flashes when the protective circuit works, so check the power indicator. If it has worked, shut power OFF, wait 1 minute or more, then reactivate the power. • dry the equipment by wiping it with a dry cloth. 7 Repairs Only the most competent and qualified service technicians should be allowed to service the factory-trained warranty station personnel have the knowledge and special facilities needed for repair and calibration of this precision equipment.
